WHY NEED IT
You can store your solar power to use when you desire, meaning you are less dependent on grid power, which makes you more self-sufficient. 14.3 /15 kwh battery system can also protects against blackouts, which can be a big concern for some people. you might have a generator, but Coremax solar battery storage bank can replace the generator with a battery. And keep your house quit with air pollution

STORING SURPLUS ENERGY IN BATTERIES FOR LATER USE | SIMPLE. RELIABLE. EFFICIENT
This 14 kwh battery bank chemistry is the safest cell technology on the market, inside with 16S gotion lfp (Guoxuan cells). CMX in particular offer higher capacity cells, higher density cells and monitor individual cell voltage rather than overall pack voltage. 14 kwh lithium ion battery utilise prismatic cells rather than conventional soft pouch cells which minimise heat build-up and thermal hotspots. This 14/15 kwh battery bank built in circut breaker, if there an short circut outside , the breaker works as an additional protection for your solar storage system. In addtional, we have included the LCD screen monitor.

10 Kwh Power wall home battery Charge& Discharge Characteristics

Battery Operation Instruction
Charging
- Charging current: Cannot surpass the biggest charging current which in this specification book stipulated.
- Charging voltage: Does not have to surpass the highest amount which in this specification book stipulated to decide the voltage.
- Charge temperature: The battery must carry on the charge in the ambient temperature scope which this specification book stipulated.
Uses the constant electric current and the constant voltage way charge, the prohibition reverse charges. If the battery positive electrode and the cathode meet instead, can damage the battery.
Discharging current
The discharging current does not have to surpass this specification book stipulation the biggest discharging current, the oversized electric current electric discharge can cause the battery capacity play to reduce and to cause the battery heat.
Electric discharge temperature
The battery discharge must carry on in the ambient temperature scope which this specification book stipulated.
Over-discharges
After the short time excessively discharges charges immediately cannot affect the use, but the long time excessively discharges can cause the battery the performance, battery function losing.
The battery long-term has not used, has the possibility to be able to be at because of its automatic flash over characteristic certain excessively discharges the condition, for prevented excessively discharges the occurrence, the battery should maintain the certain electric quantity.
Battery storage
The battery should store in the product specification book stipulation temperature range. If has surpasses above for six months the long time storage, suggested you should carry on additional charge to the battery.
Warranty
The period of warranty is 5 years from the date of shipment. Coremax guarantees to give a replacement in case of cells with defects proven due to manufacturing process instead of the customers abuse and misuse.
